MediaLab Version 2008.1

[jarvis24]

Note that MediaLab v2008.1.33c will appear as v2008.1.33 when installed. The is because the main program itself (medialab.exe) was not altered in this new release. Only the installation package was changed (i.e., ml2008.1.33.exe). To determine if you have the old or new release of 2008.1.33, check your C:\Windows\System32 folder for a file named EVideo.ocx. If it is version 1.0.0.11 dated October 7th, 1999, then you have the older version of 2008.1.33 and would benefit from the newer installation package.

Issues resolved with new installation package ml2008.1.33c:

Resolved memory issues associated with Windows 7 and Vista compatibility. Some users were finding an (approximate) 150 item limit when trying to run experiments or questionnaires in MediaLab. This revised installation fixes this issue. This issue has been a long outstanding issue on the forums. It was fixed with promising success in 2008 on Vista but returned upon the release of Windows 7. Fix relates to threads such as:

Improved video playing capability across all versions of Windows, especially Windows Vista and Windows 7.

Screen flicker experienced between items on some Windows 7 and Vista systems has been fixed.

Some Windows 7 systems produced a message indicating that, after downloading, the install package could not be found. The error message would read something along these lines:

InstallShield
Unable to save file: C:\Windows\Downloaded Installations\{53CE6DA4-...Research Software v2008.1.msi
The system cannot find the path specified. [OK]

Although clicking through the message or running the package as an Admin could resolve this, the newest release package eliminates the problem altogether.

On some systems, this new install package will generate "Error 53: Project not found" after the install has fully completed. As far as we know, this implies no functional consequence but will continue to look into the cause of the message.
