Hi All,

I have got the below error while installing the RTC Shell plugin on windows machine.

During installation, it was found that the number of registered handlers could be for icon overlays under HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ ShellIconOverlayIdentifiers greater than 11. The shell icon handler for display function after installation may not work properly

Does this error effects in not showing the icons(Source Control) on the files.

Thank you.

You can find the explanation of the issue from This is a limitation of Windows platform.

In the comment a workaround is mentioned:
The Workaround would be to edit your registry settings if you wish to show the RTC icon overlays.
Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\explorer\ShellIconOverlayIdentifiers

If you are using RTC (and have nothing else using overlay icons), you will see all of your RTC icons (at this present time 8 in total).
If you have other applications running that use icon overlays (like Dropbox or TortoiseSVN) you'll propably see those icons first (the reason why you are reading this Workaround). This is because the overlay icons are used in alphabetical order. Rename them (I suggest putting numbers in front of the ones you want to use and "z_"'s prefixed to the ones you don't need) and restart your system. The RTC Shell extensions are named 'Concert_*'.

If you use for example the DrobBox Client, this is likely to happen.
