  62 Well, after much searching and trial and error I have solved this. I'm not sure if this is the best way, but it works. Here's the scenario: I have an application I would like to deploy via a Visual Studio Setup project. In addition to my application files, I would like to create a subdirectory in the target directory that contains a batch (.bat) file. I would like this file to run at the end of the installation process. Here's what you do: Create a setup project and configure as you normally would, including the subdirectory in which you'll place your batch file (you can just place it in the Application Folder directly if you don't want it in a subdirectory). In the "File System" view (right-click on the project in Solution Explorer->View->File System), add the batch file you want to execute  and  cmd.exe (C:\Windows\System32\cmd.exe) Open the "Custom Actions" view (right-click on the project in Solution Explorer->View->Custom Ac

Masa nak run Debug mode dekat .NET, code tu ada error. Lepas tu dengan secara tidak disengajakan tertekan retrieve Reference Microsoft Symbol Server.  Lee simpan kat sini je cara nak ubah balik setting tu.. kalau lupa boleh rujuk balik Bila Run, instead of .NET execute terus application tu, .NET pergi Load Microsoft Symbol Servers. Lama dowh dia load. Jadi dekat belah atas tu, klik Tools > Options... Akan display windows Options macam kat bawah ni. Pergi ke Debugging > Symbols. Lepas tu, pilih option yang belah bawah tu.. Load only specified modules . Kalau nak untick dua2 symbol tu pun boleh je.

  I actually found a solution to this now over at   Microsoft's Visual Studio Developer Community   (Quoted relevant parts to prevent the likelihood of future dead links): 1- Open a cmd as admin. 2- Go to directory C:\Program Files (x86)\Common Files\microsoft shared\MSI Tools 3- run: regsvr32.exe /u mergemod.dll" 4- run: regsvr32.exe mergemod.dll" I followed these steps, restarted VS2017 and it worked perfectly. No more request for the VS2010 Integrated Shell installer!
