When trying to install NX, the following error message is displayed;
Error 1723. There is a problem with this Windows Installer package. A DLL
required for this install to complete could not be run. Contact your
support personnel or package vendor.
The installation then terminates.
Solution
This error is typically caused by an incorrect definition of the SYSTEM or USER variables TMP and TEMP. If these variables point to a non-existent directory, or a directory that you do not have full read/write/execute control of, then the NX installation will fail.
Make sure that the variables TMP and TEMP to point to a directory where EVERYONE has FULL CONTROL.
