I have uploaded MS Project files in my SP Foundation librarty. But when I wan't to open it in browser I get an error:
no apps are installed to open this type of link (ms-project).
How can I fix it?
There is no application to open project in the browser. What exists is Microsoft Project Server, but does not work on SharePoint Foundation. You need to install SharePoint Enterprise and Project Server . It also requires Microsoft Project Professional as a client
Sample image from MS:
A workaround for this issue is to click on the 3 dots beside the Project Name on sharepoint. Download a copy to a local drive. You can then open from the drive.
