Salaam,
There is a known incompatibility issue with Java 7 and to zekr.exe/zekrc.exe which causes the following error on Windows:
This application has failed to start because MSVCR100.dll was not found. Re-installing the application may fix this problem.
This relates to our exe file provider project, WinRun4J, and was fixed in its 0.4.3 release. To fix it, you have three options:
1. Download either of the following files and replace it on your own zekr.exe:
2. Use Zekr portable version.
3. Use zekr.bat instead of zekr.exe or zekrc.exe.
Regards,
Mohsen
