If there's an error with the License Manager, it should have generated a log file in the same folder as the License Manager's executable, which by default is at:
C:\Users\Public\Documents\Accusoft\[PRODUCT NAME HERE]\Licensing\LicenseManager\AccusoftLicenseManagerExceptions.log
or
C:\Users\Public\Documents\Accusoft\Common\Licensing\LicenseManager\AccusoftLicenseManagerExceptions.log
This will give specific error messages & stack traces that can be used to further debug the problem.
**Additionally, make sure that licensing.accusoft.com
is allowed on your server/proxy, on ports 443
and 80
.
