I have a vmware environment with 2008R2, and for the life of me I cannot get exchange installed. I have installed all the windows updates. The application crashes right after copying setup files. I open command prompt, navigate to the iso (I have even extracted the ISO to a folder on the server. I run setup.com /ps, that finishes, then it copies the files, then fails with the error in the attached screenshot. I redid the entire environment twice because it was happening, and I thought it maybe a bad vmdk. I downloaded a fresh trial of 2008R2, and also a fresh trail of exchange 2010 just to be sure......same problem.
