I'm a long time Delphi7 user.
Installed Delphi XE2 Enterprise (Plan to migrate and/or re-write Delphi7 app to EX2).
When I try to run my Delphi7 app debugger throws "error loading midas.dll'.
Question, can Delphi 7 and Delphi XE2 development be done on the same machine?
Or do I need to uninstall XE2 from my "old" development system, and use two separate systems?

Thanks,
Jeff

Addtional edits added:

I've since added "MidasLib" to the Uses section of the *.dpr files for the main executable and the 18 DLL's that comprise the application, and re-compiled them all.
So now Midas is "compiled into" the application and needs no external midas.dll.
Now I can continue to code/maintain the Live Delphi7 app while I try to migrate it to Delphi XE2, all on the some development system.

Jeff,

That's what I did.  I run RAD Studio 2007 on XP and RAD Studio XE and
XE2 on a Win7 system. 

My D2007 apps, compiled on XP, run just fine on Win7.  ;-)  But it's a
royal PITA to get XE & XE2 Win7 compiled apps to run on XP.

That would be a serious problem when developing on Win 7 and 
distributing to XP Users. What kind of problems have you seen? Is it 
with the basic Delphi features or a particular group of components?

Naw,... it's the Unicode and strings issues.  My code is OLD.

yeah, You can run two different versions of Delphi on your machine simultaneously.
 " *Error loading Midas.dll* " error Comes when the midas.dll file is missing from *'c:\windows\system32'* or from corresponding application folder. if it exists means you have to register. for that, follow the below commands,

   1. *Start -> Run -> type " regsvr32  midas.dll "* and click ok.
   Still you have the same problem ?? then
   2.  go to command prompt and type the command which given below,
   *" regsvr32  Application filepath \ midas.dll "*
