I have an old printmaster program that I use alot, now that I have win 7, it won't open because win 7 does not recognize TDT files, any ideas.
What program created those files? Is it either of the ones indicated here? http://www.fileinfo.com/extension/tdt If so you would have to see if there is a version of that program that will run on Windows 7
I tried and nothing, would I be able to install win xp, like I used to have.it was expressit??
You could try Windows XP Mode, but you would still have to install whatever program you had that created these files. They are not standard Windows XP extensions.
Thank you I'll give it a shot
