Getting “The project already contains a form or module named Unit1” error when creating new project

I am using Delphi 2007. When I try to create a new VCL Forms Application (File->New->VCL Forms Application) the IDE immediately responds with the above error.

I had this happen once before, and even thought I had asked for the answer on StackOverflow. But for the life of me can't find the answer. If I recall it had to do with an actual unit1.pas file being somewhere it should not have been.

Poking in the Delphi Options under Environment Variables BDSPROJECTSDIR is set to E, which does not exist. On another computer we have this is set to "c:\documents and ....". I tried an override but it still does not work. And I searched in the system registry for BDSPROJECTSDIR but could not find where it is set to E – M Schenkel
Strange. Have you recompiled the VCL or something like that? – Leonardo Herrera
@LeonardoHerrera - Good point. Yes - I did recompile a bpl. Not 100% sure, but it was about this time I started noticing this error. So presumably they are related. NOW - I can copy the compiled bpl to another computer and all works well. So I don't think it is necessarily related to the BPL, but when I compiled the bpl perhaps I had messed up a setting. – M Schenkel
Did you search your hard drive for unit1.pas? I'd suspect it's in the default project folder (which is in your My Documents\RAD Studio folder, IIRC), and there's a missing unit1.dfm to go with unit1.pas (or vice-versa, a missing unit1.pas with a unit1.dfm). It might also be an issue with an existing Project1.dpr that is orphaned. I'd do a search for unit1.* and project1.*, and move or rename the ones you find to see if the problem goes away. – Ken White
Did you installed IDE Fix Pack? – menjaraz

I finally stumbled up the problem. Tools->Options->Environment Options->Default Project was set to E
