This reports a very strange problem which perhaps is an OS problem rather than a SMath bug. Any idea how I could handle this problem in a more user friendly way?
At times the installation of the unofficial portable distribution https://en.smath.com/wiki/SMath%20with%20Plugins.ashx fails:
-
The ziip file is downloaded and unzipped on the local harddrive
-
The application is started.
-
A minimal SMath starts with no plugins, evensome native ones are missing.
-
-
Installation of other plugins fails, among them the development tools one, which might have given more insight.
Today 4 of 25 students taking part in an Getting Started with SMath Studio online session experienced this problem.
How to workaround: In many cases (3 of the 4 above-mentioned students) the following procedure helps. The other one has been recommended to use the standard installer and download the plugins. No feedback yet whether he succeeded.
-
Copy the downloaded and unzipped folder to a removable flash drive
-
Try to execute the program there. This usually works.
-
Copy the folder back to harddisk
-
Try to execute the program here. This usually also works.
Another workaround has been reported (private email) by a Korean guy:
Thanks for you reply.
I guessed "copy file to usb and copy back to hard drive solves the problem" is file attribute or permission related problem with NTFS files system.
So I copy unzipped folder to another directory with windows git bash's cp command e,xpecting that git bash's msys posix emulation layer clear a weird file attribute or permission.
I works.
Thank you.
