Situation:

Newest Windows 7 toolikit.

Windows 7 build 7100

getting this error immediatly after clicking on integrate...

damn, assuming you mean the latest alpha?

how much free space you got on C:\, also try deleting wimgapi.dll in the W7T Folder.

I have like 40 free gigs on c:\

Will try deleting the wimfltr file.

OK deleted the file, tried again... No good

Uninstalled\re-installed tried again... No good

Re-extracted Win7 image, tried again... No good.

I am on Windows Vista 32 bit and SP2 does that make a difference?

OK I finally found the latest beta. (I wasn't using it)

It might have worked but I have a question... I integrated the 2 theme packs without error but it took like 5 seconds. Is that really right? If so then SUPER JOB! And I am sorry for the old bug report.

Lol it's fine. 5 seconds is quick, try mounting the image normally using WIM Manager to see if it is mounting.
