How do I clean up the entries in Control Panel?
I still have Compose XE 2013 Update 15 listed as being installed, even though this does not appear in VS.
When I attempt to uninstall the older version, the uninstall fails.
You don't recall any issues during any update installation?
Re: clean-up, have you tried some freeware Windows utilities such as CCleaner? This one helps me greatly plus it is very user-friendly.
In cases where I created confusion by using a different installer for an upgrade, the solution seems to be to use the original installer to remove. Then, if old entries remain in add/remove, they may be amenable to direct removal from the Windows menu.
Having used the Parallel Studio installation, I should have waited for the PS upgrade installer before attempting any upgrades without full removal.
It might be interesting to hear whether freeware utilities help with cleanup, particularly on Win8.1.
I generally recommend the Windows Installer Cleanup Utility. This used to be provided by Microsoft but they dropped it.
