RunAsDate: How to Run a Program with an Earlier Date

Today we accumulate a lot of tools and programs on our computers that over time, many times we don’t even remember that we have them. Surely we need them at a certain time and we have not used them again. However, on many occasions, when we are going to take advantage of them, we find that they no longer work because it is a trial version or valid until a certain date. If this happened to you and you don’t know how to fix it, here is how to run a program with a date before the current one.



At the moment we are in this situation of not being able to run the application correctly, the first thing that can come to mind is to uninstall the program and reinstall it, change the system time, etc. However, we may encounter problems. Some data has been saved in the registry that although we reinstall it, we still recognize the initial installation date or that despite changing the system time it still does not work.

But the truth is that there is a way to run a program on an earlier date very easily. To do this, far from looking for some trick involved in our system, it is best to use a third-party tool that has been designed exactly for this purpose. We refer to RunAsDate .

Steps to follow to run a program on an earlier date

It is a software developed by NirSoft and that we can get completely free of charge. To do this, we simply have to go to the developer’s website and download the latest version of this tool.

This will save us a .ZIP file on our disk that we will have to unzip. Inside you will find three files, readme.txt, where we will find information on how the tool works and requirements necessary for its proper functioning, RunAsDate.chm and the tool executable, RunAsDate.exe .

Therefore, all we have to do to launch the program on our desktop is to double click on the executable file. Automatically, we will see how a window opens with its interface, which as we can see is quite simple and intuitive to handle.

The first thing we should indicate is the application we want to run with an earlier date. To do this, we click on the Browse button next to the Application field and select the program of the route of our equipment where we have it installed. Next, we define the date on which we want it to run or that we want the program to understand. That is, if we have an application whose trial version has expired on a specific date, we must indicate a date before that.

RunAsDate allows us to indicate a specific date, that is, month, day, year and even time or to indicate the date by subtracting a number of days from the current date. That is, we can indicate that the program is executed as if we were going back in time a specific number of days.

Simply by indicating these two things we would have everything ready to run the program, however, RunAsDate allows us to configure other details or options , such as returning to the current date after X seconds or at the time when the program is run, run the tool as administrator, etc. Therefore, with the always done filling in the first two fields, we can run the program on a previous date very quickly and easily.

It is important to know that RunAsDate works in:

  • Windows 2000
  • Windows Xp.
  • Windows Server 2003
  • Windows Server 2008
  • Windows Vista
  • Windows 7
  • Windows 8
  • Windows 10

Earlier versions of Windows are not compatible and there is also an x64 version available in a separate download, for use with x64 applications, from the developer’s own website.
