you could install the Platform SDK for Windows Server 2003 R2 compiler and try building Tk form source

I have (just now) managed to build Tk-804.028 for MSWin32-x64-multi-thread. If the op wants a ppm I could try emailing it over - it's about 5Mb. In tkGlue.c I had to change the one occurrence of:

#if USE_NEWSTYLE_REGEXP_STRUCT
[download]

to

#if 1
[download]

Other than that, I had to manually code in some 'bufferoverflowU.lib' links into the generated PNG/zlib/Makefile and also the generated JPEG/jpeg/Makefile to accommodate the fucking bufferoverlfowU.lib dependency. (I believe the bufferoverlowU.lib dependency won't be an issue with some compilers - but it's certainly an issue with mine. An intelligent being would be able to modify the Tk *source* to accommodate that dependency ... but not me.)

All of the tests passed - though, I had to manually code in a link to 'bufferoverflowU.lib' in the generated PNG/libpng/Makefile in order for one test to build.

UPDATE: Ditto for the latest devel Tk-804.028_501

Cheers,
