PowerISO v 9.4 64-bit lost key/license!

CCleaner for Windows
1

Hi,

When starting CCleaner, PowerISO loses the key/license.

PowerISO version of the program 9.4 64-bit.

How do I fix this problem?

I believe that PowerISO stores it’s licence as a registry entry.

Are you running the registry cleaner?

If so then stop doing that and see if the licence survives a normal clean without a registry clean.

PS. With modern Windows there is no need to clean the registry unless you have a registry problem, (or you want to remove specific entries left behind after uninstalling software).
Cleaning the Windows registry will not speed up your machine in the slightest and will only save 1 or 2 kb of space.
