I've used Cleaner for years, including of course the "scan for issues" registry part. Just love CCleaner.
Never did I have a problem with finding Uninstaller Reference Issues until I installed .NET Framework versions 2, 3.0 and 3.5 in February 2009.
When I access Add/Remove Programs just by looking at it, it creates a lot of ARP issues in CCleaner's "scan for issues".
Today I uninstalled all .NET Framework versions, accessed Add/Remove Programs and I discovered it did NOT show any Uninstaller Issues re ARPcache!!!!
Then I installed all versions of .NET Framework and guess what? CCleaner picked up the Uninstaller Reference Issues again!!!
Therefore I come to the conclusion that it must be .NET Framework (Microsoft) or perhaps something has been overlooked in CCleaner's software creation?
I have Windows XP Home, SP3
Any comments and/or advise please if anything can be done about it? Yes, I've read all the info pertaining to this issue on this forum.
Thank you.
ARPCache has already been discussed over the past couple years.
Here's some links to old threads.

Thank you for your response.
I thought that CCleaner would be interested in the fact that these problems with the ARP cache started when I installed .NET Framework version 2, 3.0 and 3.5 on February 1, 2009. My Dell machine came with .NET Framework 1.1 in 2004 and never caused any issues with Uninstaller Reference Issues in the ARPCache until I downloaded the aforementioned versions on Feb. 1, 2009. No other .NET versions were added in between 2004 and Feb. 1, 2009.
Would it be possible for CCleaner to add an option like an exemption to exempt these Uninstaller Reference Issues ARP from being shown in CCleaner as there seems to be a connection with .NET Framework as per my previous post?
Or in the very least, try to see if there is any connection because I DID see the connection today!!
Thank you.
I used to exclude ARPcache myself, however it does fill up with old gunk so I no longer do that on my system.
Here's how you exclude ARPcache in CCleaner:
1. Start CCleaner.
2. Click: Options->Exclude
3. Click: Add Registry
4. Make sure you select the HKLM registry setting from the drop down box on the left.
5. Copy+Paste the following text listed in the codebox below into the empty window.
Software\Microsoft\Windows\CurrentVersion\App Management\ARPCache

Thank you Andavari for your reply and suggestions.
I will follow your suggestion and NOT exclude ARPCache in CCleaner as it will add a lot of gunk in the ARP registry.
My workaround will be this: will untick the "installer" box after cleanup with CCleaner's registry and will tick it again about every month. Doing this will lessen my frustration by seeing those items time and time again as I use CCleaner and the Add/Remove Programs quite a bit.
I have one last question though. If one decides to exclude the ARPCache and over time wants to include it again, how does one reverse that action?
Thank you once again.
Thank you Andavari for your excellent advice and explanations. ![:)]()
