Intaller2? I don't have a NVIDIA card installed in my system anymore but I don't remember seeing a folder called that.
What is the full path name? Is that path shown in the properties for NVIDIA Control Panel?
If me, I would simply rename the folder, adding the word delete to the folder name. If something breaks, add it back. If nothing breaks, leave it for a few days to be sure all is okay, then delete it.
Alternatively, you should be able to totally uninstall your NVIDIA software forcing Windows to revert back to its native drivers. Then delete the NVIDIA stuff and install the latest from your card's website.
I think your last suggestion is a good one and worth pursuing. I asked about this b/c I noticed the entries but also saw so much talk about it after Googling.
The threads were a bit out dated though.
I used Tree Size to display the size of the folder.
Does this look as it should be. The install2 folder is in the program files. I removed the installr2 folder then force removed the program and features entries. I then booted and installed the components with driver from the NVidea site. NVidea still occupies about 1 GB total but it used to have about 2 GB just in the install2 folder.
That is greatly reduced.
When i run TreeSize, NVidea still occupies a lot of GB's. My on board video runs as well if not better than NVidea.
Would it be prudent to remove NVidea and use only the on board driver?
PS I just created an image and incised the size of the image from 17.2 to 18.5 after all that removing. What explains that?
