Original address:inno Setup, pre-uninstall detection process or service go, two or three miles.

There are a few minor problems with Inno packaging, and here's a summary: Inno.iss part of the content is as follows:

1, 32-bit program PSVince.dll plug-in method.

[Files] Source:psvince.dll; Flags:dontcopy[code]function ismoduleloaded (modulename:ansistring):  boolean;external ' [email protected]: Psvince.dll stdcall ';

2. The Psvince control cannot detect a process under a 64-bit system (Windows 7/server 2008/server 2012), which can be resolved using the following function.

 function isapprunning (const filename:string): Boolean;var fswbemlocator:variant;    Fwmiservice:variant;    Fwbemobjectset:variant;begin Result: = false;      Try Fswbemlocator: = Createoleobject (' WbemScripting.SWbemLocator ');      Fwmiservice: = Fswbemlocator.connectserver (', ' rootCIMV2 ', ', ');      Fwbemobjectset: = Fwmiservice.execquery (Format (' SELECT Name from Win32_Process Where name= '%s ', [FileName]);      Result: = (Fwbemobjectset.count > 0);      Fwbemobjectset: = Unassigned;      Fwmiservice: = Unassigned;    Fswbemlocator: = Unassigned;        except if (ismoduleloaded (FileName)) THEN BEGIN Result: = FALSE;        End ELSE begin Result: = true; End End;end;   

Here, there may be an exception:Exception:swbemlocator: Dependent service or component failed to start

Workaround refer to the following steps :

1. Run the following command at the command prompt:

CD/D%windir%system32wbem

Rename Repository Rep_bak

2. Build A. bat batch file and run it with the following contents:

Mofcomp c:windowssystem32wbemcimwin32.mof

Mofcomp C:WINDOWSSYSTEM32WBEMCIMWIN32.MFL

Mofcomp c:windowssystem32wbemsystem.mof

Mofcomp c:windowssystem32wbemwmipcima.mof

Mofcomp C:WINDOWSSYSTEM32WBEMWMIPCIMA.MFL

3. Run the following command at the command prompt:

CD/D%windir%system32wbem

For%i in (*.MOF,*.MFL) do mofcomp%i

4. Re-register the WMI component and run the following command at the command prompt:

CD/D%windir%system32wbem

For%i in (*.dll) do regsvr32-s%i

For%i in (*.exe) do%i/regserver

Installs and detects if the program is running before installation, and if run ends the process first

function Initializesetup (): Boolean;begin  Result: = true;  If  isapprunning (' {#MyAppExeName} ') then  begin    If MsgBox (' Setup detected {#MyAppName} is running! ' #13 ' #13 ' click ' Yes ' button to close the program and continue installation; ' #13 ' #13 ' click No ' to exit the installation! ', mbconfirmation, mb_yesno) = Idyes then    begin      Taskkillprocessbyname (' {#MyAppExeName} ');      result:= true;    End    Else      result:= false;  End;end;

Uninstall, similar to installation

function Initializeuninstall (): Boolean;  Begin    result:= true;    If  isapprunning (' {#MyAppExeName} ') then    begin      If MsgBox (' Uninstaller detected {#MyAppName} is running! ' #13 ' #13 ' click ' Yes ' button to close the program and proceed with uninstallation; ' #13 ' #13 ' click No ' to exit Uninstall! ', mbconfirmation, mb_yesno) = Idyes then      begin        Taskkillprocessbyname (' {#MyAppExeName} ');        result:= true;      End      Else        result:= false;    End;  End
