This is pretty vague question. But to give you some possibilities:

• Your application is not designed to be run from a path with a space in the file name (Program Files)
• Your application needs a write access to its installation folder. What it does not have, when run from Program Files. The fact that you have less problems, when running the application as an Administrator suggests this is (one of) the problem.

For a test, try to install the application to say C:\PYMEPOS.

Ntb, Inno Setup does not cache any files. Reinstalling the Inno Setup won't fix anything. I do not think your problem has anything to do with the Inno Setup actually.
