checking prior to installing a file

Recommended Posts

I have some code that I want to run an installer for only the first time the code is run.

Essentially, I need a script to run vcredist_x64 on my machine only if it hasnt been installed, and then execute the rest of the program.

I know that in Programs and Features there is a Microsoft Visual C++ 2010 x64 Redistributable 10.0.30319 after installing vcredist_x64, but I was wondering how I would check to see if it's there.

What I did was write some c++ code on VS 2010 that wont run on a computer unless the redistributable is on the machine. So I want the script to first check and see if the redist is installed. if not, install it. then run my application

Is there any way to do this?

Also, seperate subject, how do I use the "WorkingDir" section of the run command?

I would like to call the run command on the application in it's own directory, and not in the script EXEs directory. thanks

If you want to know if a file exists, then the aptly named FileExists will tell you. :blink: Depending on the returned value, you can use some form of conditional structure (If, Select, Switch) to install or not.

As for "WorkingDir", just set it to the path of the application.

would "FileExists" work when attempting to search ControlPanel\All Control Panel Items\Programs and Features ? because I have no idea where it saves the information to.

On the other hand, I've tried many different ways to get workingDir to work

run("PowerTestGUI.exe", "pwrtest\64-bit")

run("PowerTestGUI.exe", "pwrtest\64-bit\")

run("PowerTestGUI.exe", @WorkingDir & "pwrtest\64-bit")

run("PowerTestGUI.exe", @WorkingDir & "\pwrtest\64-bit")

going to try run("PowerTestGUI.exe", "pwrtest\64-bit\PowerTestGUI.exe") now, but it never works with the workingDir

If you go into the project properties, go to C/C++, Code Generation, and change runtime library from Multi-threaded dll to Multi-threaded.

This includes the runtime in your executable making it distributable without the extra installed library.

I attempted to change from Multi-Threaded DLL to Multi-Threaded (command line changed from /MD to /MT)

However, when I rebuild the code, i get an error: Command Line Error D8016: '/clr:pure' and '/MT' command-line options are incompatible.

The code was written using a windows forms application project solution. Could that be why it requires the installation?

Edit: When removing /clr:pure from the command line arguments, the windows-provided code no longer works. it seems that CLR:pure is used to compile some of the code that is microsoft syntax and not part of standard C code

Why are you using C++/CLI? /clr indicates you are using the .Net framework. C++/CLI is a mess and you should have either written the application in C# or not use WinForms.

To respond to the original question, you can check to see if it is installed in the registry at "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{6A86554B-8928-30E4-A53C-D7337689134D}"

Well this is the x86 version, but you can check your own registry for the correct GUID. Scroll through "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\" in regedit and look in each of the GUID keys until you find a display name that says "Microsoft Visual C++ 2010 x64 Redistributable 10.0.30319". That GUID will be the same on every computer. Once you know which it is, you can just check to see whether the key exists or not. If it does, it's installed.
