"Unable to open error log file" when trying to save assembly as STEP-file.

Hello,

When I try to save an assemly as STEP-file, i get the error message: Unable to open error log file to write. Make sure the disk is not write-protected. I get this error message also when i try to save it on a different disk. And i only got the error when saving as STEP-file. Saving the file as assembly works fine.

I already checked if i have administrator rights on my user account, so I believe that cannot be the problem. But what does?

Thanks in advance!
