I got a problem with the new FP 11_6_602_180. That's my scenario: It was working fine with KernelEx v4.5.2 + FF 3.6.28 + FP 11_6_602_171. On 17 Mar 2013, the system refused to start due to the notification of FP 11_6_602_180. Then I installed the FP 11_6_602_180 msi and renamed NPSWF32_11_6_602_180.dll to NPSWF32.dll. FP 11_6_602_180 failed to function. Then I tried ways to uninstall, including the standalone FP uninstaller. The uninstaller failed with R6025 pure virtual function call. Luckily, I was able to uninstall by right clicking uninstall on the msi, and then able to install FP 11_1r102_63. Now, FP 11_1r102_63 is the newest version that I'm able to set up. I was trying to re-install FP 11_6_602_171 or FP 11_6_602_168 but failed. I remembered that I was able to install FP 11_6_602_171 even with the error message: A required .DLL file, WINHTTP.DLL, was not found. All suggestion and advice are appreciated. OC
