ProblemCorel Video Studio (Pro) won't run after Windows Update (For Feb/Mar 2016) has been run. Program also does not respond to being placed in Compatibility or other mode (right-click vstudio.exe, select "Compatibility"). The issue is caused by a number of updates to a Windows sub-system that essentially breaks a link in the necessary chain of events needed by Video Studio (Pro). Problem appears to affect Windows 7, Windows 8/8.1 and Windows 10 to a lesser degree.
SolutionA 'HotFix' for Video Studio x7 or above is available from Corel here.
For Video Studio x6 or below, or in instances where a HotFix cannot be utilised, try uninstalling the following Windows Update files (
important: Corel no longer supports v6);
For Video Studio (Pro) x7 and above uninstall
3126587 and
3126593. For Video Studio x6 or below
3140410 may additionally need to be removed. Be sure to disable or 'hide' removed updates to prevent their re-install on reboot. For Windows 7, 8 and 8.1 updates this may necessitate switching Windows Update to 'manual'.

Alternative SolutionAn
unsupported/unofficial 'fix' (which may be removed as a result)
is available for Video Studio v6 or v5 users here. Download "
MUIHelper.zip" and extract the contents. Copy the included file "
MUIHelper.dll" to the root directory of Video Studio (Pro), typically "
Program Files/Corel/..." - this overwrites an existing file of the same name, rename the original to archive it before copying over the new file. Video Studio should now start (note it may also be possible to install the previously removed updates).
