can't start Oxygen (java.lang.reflect.InvocationTargetExcept

[amberink]

Hi there,

Mysteriously, I am no longer able to start any instances of Oxygen on my Win 7 system. This includes v. 13.2, 14.2, and 15.2 (yes, I have all of these...).

Any ideas on what caused this to suddenly occur and how to fix this?

Hi,

I'm mentioning here the cause and the solution in case anyone else encounters this.
The full stack trace is:

Code: Select all

The problem in this case was that the temporary folder that Oxygen uses (OxygenXMLTemp from the system temporary folder) no longer had write access for some reason.
Deleting or renaming the OxygenXMLTemp folder from the system temporary folder resolved the problem.
To quickly locate the system temporary folder in Windows, open Windows Explorer, type in the address bar %TEMP% and press Enter.
