Dear igraph team, I hope that you are well. I was wondering if would you have any advice on the issue of not being able to properly install and load igraph package. I am using the R environment in a secure AWS environment, with limited administrator rights. The R version is: 4.0.2 (2020 - 06 - 22) and the CRAN snapshot seems to be 2020-07-16, with the package being built by the 4.0.5 version. Do you think that the update of the R environment and CRAN image could resolve the issue or should I be aware of other problems that need resolving? Thank you in advance for your help. I am attaching the snapshots of the loading and error messages. ![Error](https://global.discourse-cdn.com/free1/uploads/igraph/original/1X/1dc5d0b04d429392629fd5fddaefc207b31b0e87.png) ---

This will only happen if you are using a modified version of R. I am assuming that you have Microsoft R Open. This issue is resolved in the latest igraph version, but to use it with such as old R version, you would need to compile it from sources. Note that Microsoft R Open has been unsupported for a long time and completely discontinued (the website is gone) since July this year. It is probably not a good idea to continue using it. ---
