Error while opening SQL worksheet in SQL Developer I am facing the following issue while opening SQL worksheet in SQL developer  

Popup with Error Message --> "An error occurred while opening ide.worksheet.file:/C:/users/%USERNAME%/Appdata/Local/Temp/worksheet....."

After clicking on OK I am able to continue work as usual.

I am not able to determine what is causing this problem.
I do not want this pop up coming up every time I start a new worksheet.  

Any help is highly appreciated.  

Regards.
I was also facing the same issue.
While running SQL Developer with Run as Administrator option, I was able to open worksheets.
