Hello MDL masters, I was trying to install Ms Office 2013 x86 Pro plus version on Windows 8 Pro 32 Bit version, i was able to activate Windows 8 Successfully, however I'm having trouble in installing Office 2013, when i click setup.exe see the below error message box. setup can't find or validate an installation file. please try reinstalling office from your installation source , or if you installed from a download package please redownload and reinstall. if you continue to have problems please contact Microsoft or your system administrator Even I tried with running setup.exe with admin privileges but it did not work. Could any one please help me how to fix the issue, and any other way i can install office 2013 on my PC. Thank you , Best Regards. BB.
