OK, answering my own question it was the FlexNet issue above. I ran the commands suggested and got past the point I was at before, but the installation still failed. These are the errors: fixme:storage:create_storagefile Storage share mode not implemented. fixme:advapi:LookupAccountNameW (null) L"michael" (nil) 0x33f150 (nil) 0x33f154 0x33f148 - stub fixme:advapi:LookupAccountNameW (null) L"michael" 0x186080 0x33f150 0x1857a0 0x33f154 0x33f148 - stub fixme:sxs:cache_QueryAssemblyInfo 0x17ea20, 0x00000001, L"Microsoft.VC80.CRT, version=8.0.50727.4053, publicKeyToken=1fc8b3b9a1e18e3b, processorArchitecture=x86", 0x33fa00 fixme:sxs:cache_QueryAssemblyInfo 0x17ea20, 0x00000001, L"policy.8.0.Microsoft.VC80.CRT, version=8.0.50727.4053, publicKeyToken=1fc8b3b9a1e18e3b, processorArchitecture=x86", 0x33fa00 fixme:msi:msi_unimplemented_action_stub MigrateFeatureStates -> 2 ignored L"Upgrade" table values fixme:msi:ControlEvent_SpawnWaitDialog Doing Nothing fixme:msi:msi_unimplemented_action_stub MsiUnpublishAssemblies -> 2 ignored L"MsiAssembly" table values fixme:actctx:parse_assembly_elem wrong version for assembly manifest: 8.0.50608.0 / 8.0.50727.4053 fixme:actctx:parse_manifest_buffer failed to parse manifest L"C:\\Program Files\\Tableau\\Tableau 6.0\\bin\\Microsoft.VC80.MFCLOC.manifest" fixme:actctx:parse_depend_manifests Could not find dependent assembly L"Microsoft.VC80.MFCLOC" (8.0.50608.0) fixme:ole:CoInitializeSecurity ((nil),-1,(nil),(nil),0,3,(nil),0,(nil)) - stub! fixme:wbemprox:wbem_locator_ConnectServer 0x1864c8, L"root\\cimv2", (null), (null), (null), 0x00000000, (null), (nil), 0x213e990) err:ole:CoUninitialize Mismatched CoUninitialize fixme:ole:CoInitializeSecurity ((nil),-1,(nil),(nil),0,3,(nil),0,(nil)) - stub! fixme:wbemprox:wbem_locator_ConnectServer 0x185660, L"root\\cimv2", (null), (null), (null), 0x00000000, (null), (nil), 0x1e3e960) err:ole:CoUninitialize Mismatched CoUninitialize fixme:gdiplus:GdipFillRectangle graphics object has no HDC fixme:gdiplus:GdipGetLineSpacing ignoring style fixme:menu:GetMenuBarInfo (0x20118,0xfffffffd,0x00000000,0x33cb30) fixme:menu:GetMenuBarInfo (0x20118,0xfffffffd,0x00000000,0x33cb00) fixme:menu:GetMenuBarInfo (0x20118,0xfffffffd,0x00000000,0x33cb20) err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr (nil) Not sure what the problem is now.
