Problem with borrow license for proWildfire 4

I'm not sure if it's even possible to borrow license for older versions of Creo/ProE. Whenever we generate new licenses for our customers we always end up with two license files - one that allows to run every version of Creo, but doesn't allow for borrowing license and second that supports borrowing, but allows to run only the latest version of Creo.

So, if you have license file generated for Creo 2.0 you'll be able to run only Creo 2.0 and borrow the license, but won't be able to run older versions of ProE. Maybe that's the case you can't borrow the same license for Creo 2.0 and WF4.

EDIT:

I tested it and looks like Doug is right - I was able to borrow WF4 license with my standard Creo 2.0 license. Apparently I had outdated informations Maybe the issue is then with what Martin said - check if you have variable LANG set.

Also, do not run pro_borrow as different user than the user that needs to borrow the license (eg. do not "Run as Administrator"), because borrowed license is tied to user account and cannot be transferred to another (we learned this hard way when one of our customer did exactly that and had his license locked for two weeks).

I think license borrowing came in WF2, but I'm not certain. A while ago for sure.

At the time, the license that enabled the borrowing was incompatible with older versions, so if you needed to run WF2 and WF1 or 2001, you needed the 'no borrow' license file, otherwise the standard file would do fine. As time went on, the same distinction remained but the standard, borrow enabled, file would work with all versions back to when borrowing became an option.

So, the borrow file should work fine with WF4. We run WF4, WF5 and Creo 2 here and are able to borrow a license for all. Are you running the proe_borrow.bat from the WF4 directory?
