dear All:
Sorry, I have been long to reply, but I had no notice of any reaction to my initial post.
My OS is Microsoft Windows 7 - 64 bit French version, with all updates from Microsoft installed.
Yes, I have uninstalled and re-installed Recuva 1.42.544 (64-bit), and the same problem arises: a message informing me that a new version (1.42.544) is available for download. This is the only Piriform software that causes this problem. CCleaner, Defrag and Speccy are trouble-free.
Thanks for your help!
Kind Regards,
Philippe
