After update to the CCleanerv5.38.6357 (64-bit), I noted that "ProjectLasso" was identified as "Obsolete Software" and flagged for cleaning. I recalled something about "Project Lasso" (with a space) about half of a decade ago. My research revealed that this was an issue raised by the author of "Project Lasso" (Piriform Username "dbcch").
On October 14, 2010, at approximately 2:00pm, dbcch remarked in:
"Legitimate reg key deletion - Please fix", that:
"...I once had an issue with CCleaner deleting a registry key related to Process Lasso, and you fixed that rapidly -- thank you."
"Andavari" addressed the issue.
The issue appears again. Users may be able to quickly fix by right-click, and select Exclude.
However, it would be good to attend to, and fix, the root cause.
Here is the link to the 2010 message, but I do not know if it will keep its integrity during transmission.
