I'm running 64-bit Windows 8.1 Pro, and sort of regretting having "upgraded" to it from Windows 7 Ultimate, but it hasn't been problematic enough for me to go to the bother of reinstalling Windows 7. One thing I haven't been able to figure out is how to revert a particular setting back to the default. When I installed this OS, I also installed the freeware AMD RAMDisk software, which, after using it for a few days, I remembered why I'd uninstalled it from Windows 7 before- it doesn't handle crashes very well. Now, I'd changed my temp directories from the normal ones to the R: drive (the RAMdrive), which, of course, now no longer exists since I've gotten rid of it. In environment variables, I changed TMP and TEMP back to C:\temp, but I still encounter a problem where the system acts as though there's not enough memory: when I open Excel 2013 (also 64-bit), the program itself opens fine, and I can open an existing spreadsheet and manipulate it, no problem. However, when I try to create a new blank workbook, I get this error:
Microsoft Excel cannot open or save any more documents because there is not enough available memory or disk space.
Now, certainly it's not a RAM issue because I have 24GB of RAM in this machine and am not using anywhere close to that just running Excel and nothing else, and SSD/hard disk storage is also nowhere close to full, so I suspect there's something in the OS still trying to point to the non-existent R: drive to use as a scratch/temp space to create this new spreadsheet. Does anybody know where this might be? I've looked everywhere I can think of. Thanks in advance!
