Hello,

When I try to install the Microsoft Dynamics GP on the laptop of Business Development Manager in our company, an error message appears. Please find the screenshot of the message for your reference. This type of unknown error is so annoying because I have no idea how I shall tackle the error.

Anyone has an idea to solve this error? Thanks in advance.
