I want to play Petz 5 badly, but can't because I get this message: Sorry, Petz 5 could not run because of the following error: Asset not found

Asset= \Resource\translationkit.txt This may be caused by low memory or lack of hard disk space.

My RAM is 5.75 out of 6.00 and as for my hard disk space, it's 580 GB free out of 686 GB.

This never happened on any of my older computers, so what am I doing wrong or how can I fix this?

And please, don't suggest "This game sucks! Why would you want to play that of all things? Petz 4 is so~ much better!" because I really don't care. Or "Use an emulator!" because I try to avoid them at all costs.

Remember: Windows 7. NOT VISTA!
