I have four partitions on my hard drive, viz., C, E, F and G. Partitions C and G are NTFS whereas E and F are FAT32. I downloaded wxRuby Setup to the partition E. When I tried to execute the Setup, Windows 7 displayed an error: "Unable to execute file in the temporary directory. Setup aborted. Error 5: Access is denied" I tried to execute it as an administrator by right-clicking and selecting "Run as Administrator". It again displays the same error. I brought the slider level of UAC to the lowest level to turn UAC off and restarted the PC, still I am getting the same error. I have created Windows Temp folder in the partition E by changing the Environment Variables. I did this to avoid fragmentation on the partition that contains OS. I have even changed the path of the Windows page (swap) file. I right-clicked this Temp folder to check the rights. I changed the ownership and allowed all rights, still the problem is there. I changed the Windows Temp folder location to Windows default and restarted the machine. I get the same error when I try to execute the Setup. Here please note that I am logging in as an Administrator. It is not a Guest account. How to get rid of this problem.

This issue can be caused by security programs such as antivirus and antispyware. You may temporary disable the programs and see the result. If it does not work either, I suspect that the software is not compatible with Windows 7. I suggest you contact the program publisher in this case.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
