I need to perform regression analysis for some data. Whenever I use Ordinary Least Squares (OLS) tool (spatial statistics tools>Modeling spatial relationships>Ordinary Least squares), initially the tool works fine and generates corresponding output. But after generating output, when I close the OLS process window, there appears an error message "arcgis encountered a serious application error and needs to close" and application get closed. I searched this error on google and came to know that this might be due to file permissions. I couldn't figure this out much as data file on my laptop in .csv file format have full access rights. Is there any solution except re-installing the software? I am using ArcGIS v10.1 on windows 8 (64-bit machine).

Have you started an incident with Esri Tech Support? That seems a more likely way to get a solution than re-installing. – Vince Nov 26 '13 at 18:47
Yes I have initiated the same discussion with ESRI Tech Support team as well but so far unable to figure it out – Jibran Khan Nov 26 '13 at 18:53
