Solved: driver issue windows vista
I am trying to install a driver for a resmed unit and I get this error message " C:\windows\system32\pnpui.dll is not a valid win32 application" the resmed software installs correctly but the driver for the USB connection will not. I spoke to the company and their Tech people say that I have a virus. I have run two virus checkers and a malaware checker and have found nothing. My OS is windows vista can anybody help me with this problem. thanks

A corrupted .dll could be a sign of a virus but may just be the program you are installing is not compatible with Vista. Since I don't know what application it is I can't assume or check. I do know that the pnpui.dll is directly related to the usb functions of the computer and why I lean toward incompatible driver, not .dll, and that's how the program you are installing views it with that error. There is a possibility that the .dll has become corrupted and you could attempt to replace it. This site has it.. http://www.dll-vista.com/. But I caution you about doing. You must rename the original to something else, like pnpui.dll.old for backup purposes. Most important is that you check the compatibility of the software 1st even if that includes contacting them.

Thankyou very much for the reply. I would like to tell you that I did contact the providers of the software and i updated the software to a new version. I still receive the error message as i did when i first loaded the software. I removed the software, rebooted and reinstalled the new version however I am still getting the error message. The software I use is called ResMed and it is used for dignostic purposes for sleep apena. Once again Thankyou

No problem at all, I come here only to help others. I did Google Resmed and the results were mostly related to respiratory software I do know and sorry you have a problem with something like this physically, mentally and software to add to the frustration. Please give all info you can on your system and I will spend my entire tomorrow figuring it out (no guarantees except do my best). I need your OS including service pack, every detail related to the program like exact maker and version, and maybe more importantly anything odd you have notices with your pc or have done to it before this occurred.. not looking really for opinion but just observation. I do deal with some of my own problems so can't do until the morning for reasons.

I've removed your e-mail address so you don't get spammed and also because we are an on-line technical support community and as such we provide support here on the boards where others can benefit and not behind the scenes.

Ok my bad, this is my public email and already gets bombed.. lol.. but I understand. I guess I can update this posting then. He told me he gets the same error on both his Vista machine and also his Windows 7 machine. The software creators support is telling him it's just a virus and not their fault but I highly doubt the exact same .dll's would be attacked on two separate machines by a virus. I lean toward this being incompatible software and may only work with XP. I then told him to install the Virtual XP in his Windows 7 machine and install the software and to let me know. He should get an alert from this posting but either way the answer will be stated on this forum. Thanks

Thanks for all the help. I did install the Virtual xp on my Windows Machine and have installed the ResMed software. I was able to load the driver concerned and all appears to be now working properly. Again many thanks to dncholas and to the forum for the help.
