Well duh. That was obvious once you pointed it out. Installed the newest version of Mono available in Winetricks. Still no success. Noticed that Winetricks didn't show .net to be installed, so checked the one for .Net Framework 2, and installed that as well. Now I get: Code: wine QBW32SimplestartLimited.exe fixme:shell:URL_ParseUrl failed to parse L"System.ServiceProcess" fixme:shell:URL_ParseUrl failed to parse L"System" fixme:shell:URL_ParseUrl failed to parse L"CFScan" fixme:advapi:CreateRestrictedToken (0x1c8, 0x1, 0, (nil), 0, (nil), 0, (nil), 0x2ebe8fc): stub fixme:shell:URL_ParseUrl failed to parse L"System.Management" fixme:ole:Context_QueryInterface interface not implemented {51372ae0-cae7-11cf-be81-00aa00a2fa25} fixme:ole:Context_QueryInterface interface not implemented {51372ae0-cae7-11cf-be81-00aa00a2fa25} fixme:wbemprox:wbemprox_cf_QueryInterface interface {b196b28f-bab4-101a-b69c-00aa00341d07} not implemented fixme:wbemprox:wbem_locator_QueryInterface interface {c3fcc19e-a970-11d2-8b5a-00a0c9b7c9c4} not implemented fixme:wbemprox:wbem_locator_QueryInterface interface {00000003-0000-0000-c000-000000000046} not implemented fixme:wbemprox:wbem_locator_QueryInterface interface {00000144-0000-0000-c000-000000000046} not implemented fixme:ole:Context_QueryInterface interface not implemented {51372ae0-cae7-11cf-be81-00aa00a2fa25} fixme:wbemprox:wbem_locator_ConnectServer 0x16ef68, L"\\\\.\\root\\cimv2", (null), (null), L"", 0x00000080, L"", (nil), 0x2dbdd2c) fixme:wmiutils:wmiutils_cf_QueryInterface interface {b196b28f-bab4-101a-b69c-00aa00341d07} not implemented fixme:wmiutils:status_code_QueryInterface interface {c3fcc19e-a970-11d2-8b5a-00a0c9b7c9c4} not implemented fixme:wmiutils:status_code_QueryInterface interface {00000003-0000-0000-c000-000000000046} not implemented fixme:wmiutils:status_code_QueryInterface interface {00000144-0000-0000-c000-000000000046} not implemented fixme:wmiutils:status_code_GetErrorCodeText 0x16f978, 0x80041001, 0x0000, 0x00000001, 0x2dbe1fc fixme:shell:URL_ParseUrl failed to parse L"mscorlib.resources" fixme:shell:URL_ParseUrl failed to parse L"mscorlib.resources" fixme:shell:URL_ParseUrl failed to parse L"System.ServiceProcess.resources" fixme:shell:URL_ParseUrl failed to parse L"System.ServiceProcess.resources" fixme:advapi:RegisterEventSourceW (L".",L"QBCFMonitorService"): stub fixme:advapi:ReportEventW (0xcafe4242,0x0004,0x0000,0x00000000,(nil),0x0001,0x00000000,0x829308,0x8291b0): stub fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:ole:Context_CC_ContextCallback (0x16bc68/0x16bc6c)->(0x79f277a5, 0x298cef4, {d7174f82-36b8-4aa8-800a-e963ab2dfab9}, 2, (nil)) fixme:ole:Context_CC_ContextCallback (0x16bc68/0x16bc6c)->(0x79f277a5, 0x298ce88, {d7174f82-36b8-4aa8-800a-e963ab2dfab9}, 2, (nil)) fixme:ole:Context_CC_ContextCallback (0x16bc68/0x16bc6c)->(0x79f277a5, 0x298ce88, {d7174f82-36b8-4aa8-800a-e963ab2dfab9}, 2, (nil)) fixme:advapi:RegisterEventSourceA ((null),"QuickBooks"): stub fixme:advapi:RegisterEventSourceW (L"",L"QuickBooks"): stub fixme:advapi:ReportEventA (0xcafe4242,0x0001,0x0002,0x00000004,(nil),0x0002,0x00000000,0x33f794,(nil)): stub fixme:advapi:ReportEventW (0xcafe4242,0x0001,0x0002,0x00000004,(nil),0x0002,0x00000000,0x133e08,(nil)): stub err:eventlog:ReportEventW L"QuickBooks" err:eventlog:ReportEventW L"Returning NULL QBWinInstance Handle" fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:advapi:RegisterEventSourceA ((null),"QuickBooks"): stub fixme:advapi:RegisterEventSourceW (L"",L"QuickBooks"): stub fixme:advapi:ReportEventA (0xcafe4242,0x0001,0x0002,0x00000004,(nil),0x0002,0x00000000,0x33f794,(nil)): stub fixme:advapi:ReportEventW (0xcafe4242,0x0001,0x0002,0x00000004,(nil),0x0002,0x00000000,0x133e08,(nil)): stub err:eventlog:ReportEventW L"QuickBooks" err:eventlog:ReportEventW L"Returning NULL QBWinInstance Handle" fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:advapi:RegisterEventSourceA ((null),"QuickBooks"): stub fixme:advapi:RegisterEventSourceW (L"",L"QuickBooks"): stub fixme:advapi:ReportEventA (0xcafe4242,0x0001,0x0002,0x00000004,(nil),0x0002,0x00000000,0x33f794,(nil)): stub fixme:advapi:ReportEventW (0xcafe4242,0x0001,0x0002,0x00000004,(nil),0x0002,0x00000000,0x133e08,(nil)): stub err:eventlog:ReportEventW L"QuickBooks" err:eventlog:ReportEventW L"Returning NULL QBWinInstance Handle" fixme:advapi:DeregisterEventSource (0xcafe4242) stub fixme:msxml:domdoc_setProperty Ignoring property L"NewParser", value -1 err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr 0x78144500
