Recommended: Fortect
If you see an nsis error when opening a file for writing, the following guide may help you.
Error opening file:
C: Program Files MyCompany MyApp settings
Click Cancel to stop this installation,
When I paste the file back in, the next (and next) file in the manual handles errors surprisingly well.
HOW could this be overcome? What did I do wrong while creating my story? Please help me to fully understand this error, fix and avoid these problems in the future.
Any input or advice would be appreciated.

I have been looking for a clue to this problem, but so far with no success. Please kill me if I forget the most important decision, but I officiallyI got lost and don’t understand all the problems – I hope someone from those present will shed light on their problem.
I have created an installer that works fine. However, I started to create my user guide which includes screenshots of the installation in which I need to start a fresh installation on my push computer. I write the installer and run it, everything starts. The problem is when the program starts writing files to the hard drive. Apparently there is something (possibly a permissions glitch) how I get:

Did they close your application before trying to run the installer again?

Removes the current existing installation, which will close the company and remove all files. Before running the installer, I confirmed that this file does not exist.

For one thing, someone in .onInit-Grund needs to check if you already have admin access. Requestexecutionlevel does nothing older in the operationonny systems or with disabled UAC.

Thanks for the input, I will work on this option. However, administrator access is required because the service is up and running, AND you can extend the “privileged” port. All registration data must be accessible and recorded by users. I’m not sure if this solution will have a big impact on my problem.
