Title Unable to Start ptcsetup or Pro/ENGINEER on a Windows NT, Windows 2000 or Windows XP Machine when Variable "winbootdir" is Set in the System. 
Product Pro/ENGINEER  Module INSTALLATION  TPI ID 112660  Created 22-JAN-02 
Workstation All Windows  Reported In Release N/A  Reported In Datecode  
SPR None  Resolved In Release   Resolved In Datecode  
Description
-----------------
Pro/ENGINEER or ptcsetup does not start on a Windows 2000 or XP machine if:
1. The operating system is not a fresh installation but upgraded from Windows 95, Windows 98 or Windows ME.
2. The machine has a dual boot system where a Windows 95, Windows 98 or Windows ME has been installed as first.

Note: Dual boot and Windows ME is not a certified operating system(s) to execute Pro/ENGINEER or other PTC products.

Windows 95 and 98, uses an environment variable called "winbootdir" to point to the Windows 95 or 98 loadpoint. This variable is not used in Windows NT, Windows 2000, or Windows XP. During an upgrade from Windows 95, 98, or ME to Windows 2000 or Windows XP the variable is not removed. The Pro/ENGINEER startup script and ptcsetup script in versions prior to Release Wildfire set the architecture to "i486_win95" if the variable "winbootdir" exists.

Alternate Technique
-----------------
See Resolution below.

Resolution
-----------------
If the system was upgraded from or set to dual boot with Windows 95 or Windows 98, then the variable is set in the "autoexec.bat" file. When upgraded from or dual boot with Windows ME, it is set under #Control Panel #System.

Delete the line in the autoexec.bat file that sets the "winbootdir" variable, save and reboot the machine.

To remove the "winbootdir" environment variable:

On Windows NT - Under #Control Panel #System #Environment, select the environment variable "winbootdir" from the System Variables section and #Delete.

On Windows 2000 - Under #Control Panel #System #Advanced #Environment Variables, select the environment variable "winbootdir" from the System Variables section and #Delete.

This issue is resolved in Pro/ENGINEER Release Wildfire.
