App intallation fails in Wine: Check your pif file
 

I have got wine working perfectly. I can run many apps without any problem. However, when I am trying to install one Win app through wine, I am getting the following error:

16 bit DOS subsystem:
C:\windows\temp\dosshell.pif
Invalid program file name. Check your pif file.

The pif seems to be in some weird format. Cat produces following output:
cat "/[path to wine dir]/C-Fake Windows /windows/temp/dosshell.pif"
�C-Install DOS shell ��COMMAND.COM �P�MICROSOFT PIFEX�qWINDOWS 386 3.0�h��d(# WINDOWS 286 3.0!INDOWS VMM 4.0��7�PIFMGR.DLL2��

I am using Ubuntu Dapper.

Any ideas?

.pif is program information file used by windows mostly to run dos programs in windows environment

In your case the file probably wants to spawn a dosshell
(I dont know how to resolve your error but thought above info may help)

Ok, thanks for this bit. I knew something about the pif files, but it is over 10 years ago I was dealing with them last time. It may be that this program has old win installer that requires dosshell. Thanks for your tip =)
