After successfully installing RadControls_for_ASP.NET_AJAX_2009_2_826_trial.msi in Windows Vista Ultimate SP2 I took the exact same msi and tried to install it on Windows Server 2003 R2 SP2, but this time, after seeming to start fine, it puts up the following error pop-up:
The cabinet file 'media1.cab' required for this
installation is corrupt and cannot be used. This
could indicate a network error, an error reading
from the CD-ROM, or a problem with this
package.
Retry Cancel
No amount of Retry attempts helps.
Please don't tell me to download a fresh copy. This is the exact same MSI file that had zero problems installing on Vista SP2, so I am 100% confident that the msi is not corrupt.
