I tried to upgrade yesterday from 3 to 3.1.
First the download assistant had “corrupted files,” then the direct download from the “download Dorico” page on Steinberg’s site had “corrupted files” (“checksum error”). At the advice of Steinberg Phone tech support, I reset Windows (thereby hosing all my other apps, including my alternate software, Sibelius 7.1).
I still have checksum errors, no matter how many times I redownload.
I tried completely uninstalling and reinstalling the download assistant, which also didn’t work.
I’ve tried booting into safe mode with network access,
I’ve tried disabling ALL firewalls, including the one on my internet router, as well as ALL of Windows Defender (firewall, virus scanning, etc,).
I’ve tried redownloading after I reset Windows, while in safe more with all the firewalls and antivirus disabled.
I have tried checking and repairing my hard drive using chkdsk /f and chkdsk /r from the command line, and then re-downloading while in safe mode with all firewalls and antivirus disabled.
I still can’t reinstall Dorico (“checksum error”), and of course, the reset wiped my original installation.
I think the checksum itself is the issue, or perhaps Microsoft’s checksum checker.
I lost an entire day of productive writing time, which would have been billable at my normal hourly rate. I have lost access to the last 15 years of intellectual property I created in Sibelius before I switched. I have had to drop a commission that I could have had finished by deadline otherwise.
Someone please help me.
