1. I have Oracle 10g form installation copy (10.1.2.0.2) (also downloaded latest copy from OTN) and change the oraparam.ini and added 6.1 in Windows.I did not change the oraparam.ini and was able to successfully install Forms 10g R2 on Windows 7 (32) by simply following the installation instructions for installing 10g on Windows Vista - with the addition of instructing the installer to "Run as Administrator". The key, is running as the administrator because Oracle Forms is not written specificially for Windows 7. Consequently, the installation will attempt to write files to Windows protected directories and the User Account Control (UAC) mechanism in Windows 7 will block writing files to these protected directories rather than virtualize them. By running as the administrator, UAC will virtualize (writing these files to safe locations and reference the files from these safe locations) files rather than block them. I would bet, that your installation terminates abnormally, becuase the writing of files to protested directories was block instead of virtualized. Try installing again and select the "Run as Administrator" option.
