If your installation is distributed over the internet and you're getting a lot of reports of this error, it could be that your web server is delivering partial files by dropping connections prematurely.
Have the affected users check the size in the bytes of the file s they downloaded. Additionally, a new uninstall log file unins???. The obvious solution for this is to not change AppId or AppName. This message normally means that you specified the "regserver" flag on a file that doesn't possess the ability to be registered. Remove the "regserver" flag from the [Files] entry and the message will go away. From Tim Rude: The simplest way to get a batch file to automatically close on exit is to clear the screen at the end of it using the CLS command.
At startup Setup looks in the registry to see if the same application was already installed previously, and if so, it will use the directory of the previous installation as the default directory presented to the user in the wizard. If you uninstall the application and run Setup again, it will use the new DefaultDirName setting.
If you wish to disable this feature, set UsePreviousAppDir to "no". Two files can't have the same name, and since shortcuts are files, two shortcuts therefore can't have the same name.
First, make sure that you are not using the "nowait" or "waituntilidle" flags on the [Run] entry. These flags prevent Setup from waiting until the process completely terminates. If you aren't using those flags and it still doesn't seem to be waiting for the program to finish, then likely what is happening is that the EXE you're running is spawning some other process and then terminating itself immediately, causing Setup to think the program has finished. Your installation requires administrative privileges and is running elevated: Mapped drives are not available by default to any elevated application.
This was introduced in Windows Vista. There is an option to make them available for same user elevation, but this won't help the situation when run from a LUA where the user changes. Use the Pascal Scripting feature or the [Run] section:. The [Run] section is an oft overlooked yet simple method of performing custom installation tasks.
First, write a small program in the development tool of your choice preferably one that creates stand-alone EXEs, such as Delphi that performs the desired task, and copy its EXE to your script directory. Then add a [Run] section entry, telling Setup to execute the EXE after all other installation steps:. You could alternatively incorporate the installation task into your application's main EXE and have it perform the task when called with a special command line parameter.
For example:. This happens because in Windows, wildcards match both long filenames and 8. By default, a file named "webpage. To avoid this, add an Excludes parameter to explicitly filter out files with an. Add the createallsubdirs flag to your [Files] section entry, and the empty directories will be created at install time.
Compare the version numbers on the existing file and the new file by right-clicking them in Windows Explorer and selecting Properties. By default, Inno Setup will not replace an existing file unless the existing file has no version info or has a lower version number.
The log will show the binary version numbers of files and why certain files were not replaced. If you want to force a file to be replaced regardless of its version number, add the ignoreversion flag to the [Files] section entry. This flag should only be used on files private to your application, never on shared system files. First set the [Setup] section directive "ChangesAssociations" to "yes".
Then create 5 [Registry] entries as shown below to create a file association. Environment variables are stored as string values in the registry, so it is possible to manipulate them using the [Registry] section. System-wide environment variables are located at:. Inno Setup does not currently have a specific feature for doing that, but you can make a copy of a file before it is replaced by using a [Files] section entry similar to this:.
See the Common Parameters topic in the documentation for details. The [Dirs], [Files], and [Registry] sections support Permissions parameters for setting permissions on directories, files, and registry keys respectively. If you have more advanced needs, take a look at SetACL. You may run a batch file by specifying the filename directly in the Filename parameter of a [Run] section entry:.
This is because each user session has its own kernel namespace. A like-named mutex must also be created in the session namespace i. Additionally, a special security descriptor must be passed in each of the CreateMutex calls to ensure the mutex is accessible by different users.
We need our mutexes to be accessible to all users, so that the mutex detection can work across user sessions. To do this we use a security descriptor with a null DACL. A typical Inno Setup installation does not require administrative privileges. However, there are exceptions as noted below. Inno Setup itself does not require write access to the Windows directory, or any other registry key not mentioned above.
What is different when an installation is run by a user without administrative privileges? Also see the Non Administrative Install Mode topic in the documentation for details. Inno Setup places no arbitrary limits on how many files, shortcuts, registry entries, etc. When Cancel is clicked, Setup will begin reverting changes it's made so far in the very same manner as the Uninstall program. Thus, a partially installed application isn't left over.

See How to force Inno Setup setup to fail when Run command fails? Thank you for your feedback. While it might work, I think it is an overly complex way to do things. Writing return codes to files, reading them back, etc. I would rather work with a simpler piece of code, like suggested here: stackoverflow.
However, it's also somewhat ugly to launch a dummy program first. Is there no cleaner way to call the Exec function from a [Run] line? So use the answer by TLama with the improvement suggested by Nyerguds. I assumse you mean to do it like this then: stackoverflow. Maybe I should copy a dummy file RunCommand1.
