The Installation Manager failed to register sldfuncfeat.dll

Hello members,

When I'm trying to install Solidworks 2015 Education version I get the following error:

The Installation Manager failed to register sldfuncfeat.dll

"C:\Windows\system32\regsvr32.exe" /s "C:\Program Files\SOLIDWORKS Corp\SOLIDWORKS\sldfuncfeat.dll" returned 0x3

I've tried running the setup as administrator and I've turned off my antivirus software, both options didn't work.

Does anybody know how to solve this problem?
