To anyone who were not able to get "Reread License File" to work.

First. Be sure the computer name in the "orcad16.lic" is entered correctly and has a space before and after.

Second. Be sure you changed the path to the license file in the correct tap in the License Manager Tools window. It is NOT the first tab.

I struggled with it for an hour and finally got it. Everything works perfectly.

Followed all the instructions and stuck in the License manager tools section: It says "You need to be a administrator to perform this function", but the thing is I'm running the app on my administrator account.
PLZ help. Need this software bad.

confirmed working on win 7 x64 ultimate..
follow instructions precisely and you'll get there..
for people who cant find a setup file in the beginning should just install power iso or similar software to unrar the cd1's files..

@karmacash
run the license manager tools by right clickin on it and then select run as administrator in the start menu

For those who still cant get this working after all the steps provided should do this:

1. Right click on My computer icon and go to properties.
2. then advanced system settings.
3. click on environment variables.
4. double click on CDS_LIC_FILE variable and change the path to the orcad16.lic file present in your c: cadence or orcad licensemanagerorcad16.lic

then run softwares. they should run now.

Thanks to the uploader. hail piratebay!
