FGTech Galletto 4 v54 cannot Be Installed (Solved)

I have described my problem about installing FGTech Galletto 4 v54 with error “DeleteFile failed; code 5” and advised solutions from engineer in this blog. Sincerely hope to help people with the same issue.

Problems description:

The FGTech V54 can’t be installed with the error followed:

An error occurred while trying to replace the existing file: DeleteFile failed; code 5.

Click Retry to try again. Ignore to skip this file(not recommend), or abort to cancel installation.

Every time, I clicked the installation. The time on CP was changed to 12/2012

Advised solution:

1Do not mind the changed time. It’s the usual situation.

2The operation system should be windows XP.
