Is there a trick to installing SP1 64bit for exchange 07? I have it downloaded and extracted to a folder but I cant seem to get it to run. Does anyone know what I am doing wrong?Thanks,Tommy

try running setup.com /:upgrade from a cmd prompt so you can see what its doing. Also, you can have a look at your setup.log file.

sorry thats /m:upgrade

When I do that it says that "there is a version mismatch between the running application and the installed application".

you sure you've got x64 windows, and x64 sp1? the server is already running e2007?

Yeah I am positive. I cant even get the install to start.

I know for sure that the OS is 64bit is there an easy way to tell if exchange2007 is 64 or 32? And I know I have the 64bit sp1 version it says 64 in the executable file name.
