[ericamortosen]

Bro, i am facing problem with registering the "regsvr32 isdone.dll" into the command prompt. it is saying -

" The module "isdone.dll" was loaded but the entry-point DllRegisterServer was not found.
Make sure that "isdone.dll" is a valid DLL or OCX file and then try again."

To all the one suffering do one thing....when you change initial memory change to 100 and next memory according to the space available in the disc you install the game ...mine was 171 free so I put 17100 ...I have done every ways and this worked...

"Dllregisterserver was not found"

[HeyElii]

After hours of struggling I finally found the right video and solved my problem thank you so much.
I did 2 steps differently, for my initial size of memory I put 100 and maximum size I put the size available on my drive where I was installing the game to. In my case I had 171gb free, so I put 17100. And I runed the
regsvr32.exe /s
regsvr32.exe /s C:\Windows\system32\unarc.dll
