Unable to open the CAD file

The drawings sent from the design institute show \"MUST re_cover\" when opened; I’m not sure why. I’d appreciate advice from those with more experience.

1# dykl087245h I’m not sure~ I’ve never used it before. Could you please send me the file? My email address is nomar@yungloong.com.tw. I’d like to give it a try. Thank you

Then try to recover it

3# borger: I checked, and someone shared that you can create a new file, type “recover” directly on the page and press Enter; this will open a window where you can select the file you want to recover. If that doesn’t work, it means the file is damaged, and you may need to try again. I just tried your file, but it didn’t work – it still couldn’t be opened

MUST re_cover! Repair of drawings infected by the virus. Symptoms of the virus infection: When opening a drawing, only one sentence in English is visible on it: MUST re_cover! The virus is caused by acad.vlx. Method to remove the virus: Step 1: After closing CAD, search for acad.vlx throughout the system, and then delete all instances of acad.vlx that are found. Step 2: Usually, there is a logo.gif file in the Help directory; delete it as well. Methods to save graphic files: 1. After closing CAD, search the entire drive for acad.vlx files; rename one of them as a.vlx to keep it, and then delete all the acad.vlx files that were found. 2. Restart CAD, open the corrupted graphic file, go to the “Tools” menu and select “Load Application”, choose to load the backed-up a.vlx file, and enter re_cover in the command line to restore the disrupted and hidden drawings. 3. After all the corrupted files have been repaired, close CAD, then search for acad.vlx throughout the entire drive once more, and delete all instances of acad.vlx that are found. Special note: 1. The above method is only applicable to machines directly infected by the acad.Vlx virus and the drawings on such machines that have been infected; it is not suitable for sending the infected drawings to other machines for repair, as the drawings themselves do not carry the virus – it is the CAD program on the local machine that is infected ; 2. If you wish to restore drawings that have been damaged by a virus from another machine, in addition to finding the virus file acad.Vlx, you also need to locate one of the following files: acad.lsp, acadappp.lsp, or acadapp.lsp. This is because the Vlx file is the main executable program of the virus, while these LSP files contain the commands that define how the virus program operates; they must be used together ; 3. The emergence of this virus also serves as a reminder to us: always keep backups, and in particular, do not disable the BAK files used for CAD backups, as these BAK files can become the last hope in cases when recovery is no longer possible ;
