I have been using CCleaner Portable for a long time now. I have noticed CCleaner Portable has started storing registry entries even though its portable. Could you please fix this.
The portable version I use is from the official website https://download.ccleaner.com/portable/ccsetup569.zip and this is the registry entry stored by it [HKEY_LOCAL_MACHINE\SOFTWARE\Piriform\CCleaner]
Do you have the portable.dat file (it's 10 bytes) and should be in the directory where CCleaner.exe is stored? It tells CCleaner it's portable, without it registry data will be created.
portable.dat contains this in it (should you need to create it for yourself):
#PORTABLE#
Yes, I have the portable.dat file in the CCleaner directory. I have noticed this registry creating bug for portable since the 565 version, haven't noticed it in the 553 version.
Something else for them to fix then.
