Whener I am trying to open the parallelLinkDesigner, it is throwing the below error:

Hi @Thivakar,

It looks like you're running into an issue with Parallel Link Designer in MATLAB R2023a. The memory recommendation is just that—a warning. MATLAB sometimes gives out random memory allocation suggestions, this warning can be ignored.

The issue regarding MATLAB shared engine can be resolved by upgrading to the latest version. There was a bug related to this issue in earlier versions, and even after some updates, it still exists in R2023a. However, upgrading to the latest version (R2023a Update 2 and later) should fix it. You can check out more details here:

The below possible workarounds maybe used if upgrading MATLAB is not feasible:

1. Network Connection: Make sure your computer is connected to a stable network.
2. User Account Groups: Check the groups your Windows user account belongs to. This might help if there are any permissions issues. You can follow this guide to see which groups your account is in: https://web.archive.org/web/20230401202240/https://www.howtogeek.com/tips/how-to-see-which-group-your-windows-user-belongs-to/
3. AzureAD Account: If you're using an AzureAD account instead of a local user account, this might be causing the issue. Switching to a local user account could help.

Hope it helps!
