I heard back following from support
"I noted when we spoke last week that you were interested in whether updates would be available through Symantec Installation Manager (SIM). These hotfixes will not be available through SIM. I expect that the next Service Pack will be, but not these hotfixes.
As a pcAnywhere Solution customer, you can download the latest hotfix to your Notification Server from the KB article, and then you have the options of using a Managed Software Delivery policy, or perhaps a Task, to deliver the MSI file to managed computers and run it."
seems a bit ridiculous to me since I just installed another hotfix for PCAnywhere through SIM around when SP2 came out. How does this one not rank important enough to push to customers ??
