...Vista Home Premium or better works fine...
Hello Becky,
IF your running a top level Virus software, you can limit Vista's intrusion upon any Internet & program software.
You need to go to the Security department, and disable User Accounts(UAC). It is an overkill, designed to make you think about your activity, not only on the Web, but with everything you do, on Windows.
You can so do this, after you have correctly installed TRS2006, and SP1, even Windows SP1 for Vista.
I don't even get a Open dialogue, whilst opening TRS2006.
I'd suggest installing TRS2006 into your File C:/TRS2006
Not the default Program Files installation.
You can just drag & drop the files into a new folder you create on file C: It runs faster, and takes less memory that way...
