General Description: During the installation of 2.1i, the installer fails with an error: Unexpected error occurred Looking in the setup.log file, the first error message is:
Win32NativeCodeException: couldn't convert MS registry value to java error: com.xilinx.xinstaller.xinstaller.XIRuntimeException
A problem has been found on some PCs where there is an entry for the Environment in the Registry that is either of an invalid type or is not correctly set. The install program does not recognize this type, and fails.
The fix is to re-update the Registry. This can be done (on NT) by going into the Control Panel, System, Environment tab.
In the System Variable section, there should be a PATH variable listed. In the User Variable section, there should be both TEMP and TMP variables. Typically, clicking on these variables, and updating them should re-set the value in the registry, and clear up the problem.
If the above does not work, and there is not a PATH variable listed in the User section, then create one. Click on the Variable, and type in PATH. Then click on the value, and type in %PATH%.
This should force another update of the registry, and correct the problem.
