exception when installing license

Hi,





I received an academic license file and managed to install it for the Instant JChem package on one computer, but it doesn't seem to be letting me do it again for a different computer. I keep getting a Java exception:

It seems like a similar problem as this thread,

But, I'm already using the workaround trick of starting the LicenseManager through Instant JChem's Help|Licenses. With other applications, it just hangs. Is there a way to install the license manually?

Hi Chris,





we are sorry for the problem, we will fix it by the 5.1 version.





The license installation is simple manually as well, just copy the license file to the location: C:\Documents and Settings\grdevipr\chemaxon\license.cxl





Somehow access is denied for the license installer to do the same.


Please tell us if this solves the issue or not.





Kind regards,


Judit

Hi,





Thanks! That was kind of a weird problem. The chemaxon directory only had permissions set for SYSTEM and nothing else. After fixing those the LicenseManager works fine.





Best,


Chris
