I'm new in forum, I would like say Hello! Currently I learning about SCCM2007, I installed my first SCCM site server in lab envinroment. All installation was successful, installation was based on server 2008R2 and SQL2008R2, but i have problem with software distribution. When I deploy software for client (Win7) i receive information in "Run Advertised program" in control panel that software is ready to install but when i click install i have information that file not exist. I checked all configuration in SCCM2007, check DP config, and I don't know what is wrong. All firewall are disabled on all servers are disable! Client conenct to the site server is properly, client actions tab contain more than 2 policies therfeore i suppose that connection to the server is OK, package also was added to distribution point. I have some log from client system, from execmgr.log Invalid executable file "Firefox Setup 16.0.exe" execmgr 2012-10-12 17:06:23 4060 (0x0FDC) Raising event: [sMS_CodePage(852), SMS_LocaleID(1045)] instance of SoftDistProgramBadEnvironmentEvent { AdvertisementId = "LAB20001"; ClientID = "GUID:185924F7-F7BB-42B1-871B-BD01012DE9F5"; CommandLine = "\"Firefox Setup 16.0.exe\""; DateTime = "20121012150623.912000+000"; DriveLetter = ""; MachineName = "CLI2"; PackageName = "LAB00003"; ProcessID = 1384; ProgramName = "firefox -apps"; SiteCode = "LAB"; ThreadID = 4060; Win32ErrorCode = 2147942402; WorkingDirectory = ""; }; execmgr 2012-10-12 17:06:23 4060 (0x0FDC) Raised Program Bad Environment Event for Ad:LAB20001, Package:LAB00003, Program: firefox -apps execmgr 2012-10-12 17:06:23 4060 (0x0FDC) EnterRsRuningState failed to run script "Firefox Setup 16.0.exe" 0x80009106 execmgr 2012-10-12 17:06:23 4060 (0x0FDC) OnOptionalExecutionRequest failed at EvaluateRequestForExecution execmgr 2012-10-12 17:06:23 4060 (0x0FDC) OnOptionalExecutionRequests failed for program firefox -apps execmgr 2012-10-12 17:06:23 4060 (0x0FDC) Please help, many thanks for any advice, cheers
