[pcguide2]

During upgrading to newest version (1.2.2.2) got this error.

Error opening file for writing:
C:\Program Files\Ultracopier\PluginLoader\catchcopy-v0002\catchcopy64.dll

Error can be skipped but what was causing this?

Hello,

Yes, this can be ignored.

Would you like to say what is causing the error?
Is it safe to use program to copying files or is that [error] affecting them somehow?

It's the Windows API, this dll is for redirect the copy/move and paste to Ultracopier/Supercopier.
Then the only affected part is redirect the copy/move and paste to Ultracopier/Supercopier. It's safe to coping files.
