Try the suggestion posted by @nick_666 over here. i was getting similar issues, and removing all appdata folders helped solved my problem.
"Sometimes just doing a reinstall doesn’t help, so try to use any “Registry cleaner” to remove previous traces of Infinity from the registry.
Before you re-install Infinity, kindly remove and delete ALL previous traces on your system (use any REGISTRY cleaner/repair tool, if need be).
Go to the following location and path, and manually delete both the “Daring Development” and “Infinity” folders, if they are still there.
C:\Users\Your- Windows USERNAME\AppData\local\Daring Development, as well as C:\Users\Your- Windows USERNAME\AppData\local\Infinity.
Look for the ROAMING folder as well, under AppData. Remove the CACHE folder.
Some folders can found under “Roaming” as well, e.g, . C:\users\Your username\AppData\Roaming\Daring development\Infinity\CACHE.
Check this installed path as well, i.e. C:\Users\Your UserName\AppData\Local\Package cache{some random numbers} folder, if this has been created."
