I'm using photoshop 7.
All the adobe CS products includes the macrovision spyware "safecast" which can prevent the computer to boot (specialy on RAID and using TrueCrypt), as it write a signature in the boot disk sector.
Uninstalling CS does not remove the signature.
quotes from a newsgroup:
"Each time Photoshop is started, SafeCast takes an inventory of the machine it's installed on, and will refuse to load the application if it decides too much has changed."
"The cracked ISO file posted in various places on Usenet does not stop the signature from being written, but after the modified files are copied into the installation folder, the signature is no longer checked, nor is it ewritten. Absolute sector 32 can be overwritten and CS still starts and works normally."
"System admins who are working with multiboot systems or custom boot loaders should install their other OSes only after both Windows and CS are installed. If another operating system or a custom boot loader writes to sector 32, CS will no longer start. In this case, the cracked version of CS is the only available workaround."
I like this one
"Also, those who wish to completely backup their drives will need to use Ghost's "forensic copy" option, by specifying the "-id" switch on Ghost's command line. Note that a standard disk or partition image backup will _not_ copy the SafeCast signature, and if the disk or partition is restored to another physical drive, reactivation of CS will still be required...".
I'm on Raid5, I don't want to try it, even if I don't use trueCrypt.
I just don't like DRMs like softwares, the "Adobe LM Service" can be deactivated, but it re-enable itself when running CS product.
