Question:
I inserted MegaMix CD-ROM #1 into the CD-ROM drive and it does not start. How shall I proceed?   
Answer:
Run the installer by choosing install.exe from the root of your CD-ROM drive. E.g. type d:\install.exe in Start : Run dialog box (if your CD-ROM drive is denoted D:)


Question:
I installed MegaMix but cannot find its icon to start using the program
Answer:
Choose MegaMix : SuperMemo on your Start menu (on Windows taskbar which you can open with Ctrl+Esc)


Question:
MegaMix installed OK but I cannot find out how to start using French and Spanish collections
Answer:
At installation, you must remember to check those collections in the tree of all collections to install (by default only ABC of SuperMemo installs). Once you install French and Spanish, use File : Open in SuperMemo to locate and open French.kno and Spanish.kno and choose Learn. Remember you will need Disk #2 in your CD-ROM drive to have sounds and pictures in multimedia collections.


Question:
I installed all collections of MegaMix and when I choose File : Open I seem to see dozens of folders but no files to open
Answer:
Each SuperMemo collection is made of a file <collection name>.kno and a folder. For example, Basic English.kno and [Basic English]. In File : Open you must locate the kno file (e.g. Basic English.kno). Because Windows displays folders before displaying files, installing 300+ collections will make you either scroll through all those 300 folders or simply type the name in File name field. Once you do it, you can select files from the picklist on the File menu (up to 10 recent collections are listed there). (note that picklist does not show in the Beginner level)


Question:
Can I upgrade my Advanced English 97 to Advanced English 98 available from MegaMix?
Answer:
Yes. You will have lost some items that have been removed or modified in the new version. As for the material you have modified yourself, you will have to either transfer it (using browser tools) or introduce the corrections manually using the learning process transfer report


You can manually copy collections from the MegaMix to SuperMemo 2000 folder (#6203)

Question:
How I can easily begin using the collections of the 2 CD MegaMix SuperMemo set with my SuperMemo 2000?
Answer:
You have two major options: 

1. copy collections manually from MegaMix to your sm2000\systems\ folder (manual copying will spare you version confusion) 

2. installing SuperMemo 98 alongside SuperMemo 2000, using MegaMix installer and copying collections with SuperMemo 2000 (if you use the MegaMix installer, delete sm98.exe file after installation to make sure you do not confuse versions and formats) 

Manual installation: 

Installing collections manually: copy the <collection>.kno file and the <collection> folder to any folder on your hard disk (preferably to the systems subfolder of your SuperMemo 2000 folder). For example: to install Japanese Hiragana, copy the file \japanese\hiragana.kno and the directory \japanese\hiragana to c:\sm2000\systems\ (you will arrive at: c:\sm2000\systems\hiragana.kno and c:\sm2000\systems\hiragana). Some multimedia collections will yet require setting the pointer to your CD-ROM drive (use Tools : Options : Data access : Secondary storage and change the drive letter to point to the correct CD-ROM drive where you keep CD-ROM #2). 
Important!
After copying collection files from CD-ROM to your hard disk, you have to turn off the read-only attribute on collection files. Otherwise, SuperMemo will not be able to open such a read-only collection!


Question:
How can I get sound for Advanced English 98?
Answer:
You will only need to use CD-ROM #2 of Advanced English 97 (we will introduce a special upgrade offer) and change the Secondary Store to your CD-ROM drive letter


Question:
How much hard disk space does MegaMix use?
Answer:
All collections take 1.3 GB space of which about 500 MB is installable on user hard disk. However, you can choose only collections that interest you. The minimum installation is 10 MB. Advanced English 98 takes about 30 MB. Other collections usually take from 0.3 MB to 3 MB. The setup program shows you the space required as you select individual collections


Question:
When I try to install MegaMix I get Range check error!   
Answer:
Unfortunately, there is a bug in the installer that shows up in rare cases on old copies of MegaMix (those replicated before January 2000). Please read more: MegaMix Installer Bug  


(Marjolein Hoekstra, the Netherlands, Nov 2, 1999)
Question:
I ordered SuperMemo 99, MegaMix 99 and Advanced English 97. I would like to learn Advanced English in optimum configuration. Can you advise?
Answer:
The optimum sequence is this:

  1. Install MegaMix and choose Advanced English 98 during the installation (this will provide you with the newest version of Advanced English texts)
  2. Delete sm98.exe and put sm99.exe in its place (this will make sure you use the newest version of SuperMemo). All collections will be upgraded automatically when you open them
  3. Open the collection ae98.kno (Advanced English 98), insert Disk #2 of Advanced English 97 to a CD-ROM drive and in Tools : Options : Data Access : Secondary storage provide the CD-ROM letter (this will connect Advanced English 98 with the CD-ROM #2 of Advanced English 97, which stores 27,000 sound files of this collection)

Question:

I have SuperMemo for the Palm Pilot, and was wondering if I can use the databases in the MegaMix CD on it. Or if only some of the databases will work, about what percentage?
Answer:

A large proportion of collections from MegaMix can be imported to Palm SuperMemo. For this purpose, you will need to install MegaMix in Windows and use File : Export : Q&A text (in SuperMemo for Windows) to export collections in question-answer format. In case of language learning collections, you will lose sound that illustrates individual items. Palm SuperMemo database can have up to 64,000 items. In practice, you are limited by the available memory of your device and the speed of your HotSync process. Unless you use some 3rd party tool to speed it up, syncing about 10,000 items may take some 15-60 minutes, depending on your Palm model version


You cannot open SuperMemo read-only collections (#6020)
Question:
I am using SuperMemo 2000 and tried to open the file below from the MegaMix CD-ROM. SuperMemo has just displayed the following error: "Fatal error! Cannot create registry: F:\English\Languages\Basic Spanish (AudioVisual)\registry\comment. File access denied"
Answer:
You cannot open collections whose files are marked read-only (as opposed to collections opened in SuperMemo's read-only mode). You need to install them on your hard disk first (e.g. with MegaMix Setup or manually by copying)


After copying collections from a CD-ROM, you need to remove their read-only status (#237)
(Chuck Albritton, Wednesday, August 22, 2001 3:36 PM)
Question:
I manually copied a collection from MegaMix CD-ROM. I received the following message: "Old system structure detected. Upgrade is impossible due to ReadOnly status"
Answer:
All you need to do is to remove the read-only status from the collection files (copying in Windows preserves file attributes). If you are using SuperMemo 2000, collection files need to be upgraded from MegaMix's format (SuperMemo 98) to SuperMemo 2000 format. "Old system structure detected" indicates that SuperMemo 2000 recognized older file format. "Upgrade is impossible due to ReadOnly status" indicates that SuperMemo 2000 cannot proceed with the upgrade due to the fact that collection files are marked as read-only. To remove read-only status, select the relevant files in Windows Explorer, choose Properties and clear Read-only checkbox


You can use Secondary Storage in Options to find files from CD-ROM (#6434)
(Chuck Albritton, Wednesday, August 22, 2001 3:36 PM)
Question:
I manually installed a collection from MegaMix but the art pictures would not appear, nor would the audio sounds
Answer:
Use Tools : Options : Data access : Secondary storage to specify the path to the multimedia files on CD-ROM (this path is normally set automatically by MegaMix installer). Click on the search folder button on the right, select the CD-ROM drive letter and search for the relevant folder. Choose the ELEMENTS subfolder. Note that MegaMix keeps collections on two CDs. Some large collections may be split between those two CDs. For example, collection data is stored on CD #1, while its multimedia files are stored on CD #2. Alternatively, you can copy multimedia files (i.e. ELEMENTS folder) to your hard disk and set the secondary storage to that location
