yukijocelyn asked:


There are some software for example of TrueCrypt that I have tested that can be installed into Windows 7 RC version, but cannot be installed into Windows 7 RTM version.
I need to know what is the difference between these 2 version, in terms of their services and or another other factors that can attribute to such an error in the installation of TrueCrypt in Windows 7 RTM version.

Can anyone help?
Thank you!

    RC is the Release Candidate. This is not the final build but not far off and is offered freely to try from Microsoft. This will however expire in march 2010.

    RTM is Release to Manufacturing which is effectively the final “gold” build of Windows 7. This copy was given to OEMs to being preinstalling it on New PC’s and is the game version that will hit the shelves for retail on the 22nd October.

    The problem is the small partition of 100mb. If you delete it and manually create a partition you then choose for win 7 (all during setup - will only work if you boot from usb key or dvd, not start install from another windows copy) the small partition will not be created and truecrypt will recognize the boot partition.

    The RC is essentially a testing version. RTM is the gold version that actually ends up getting sold as the final product.

    Multiple changes, bug fixes, etc. occur between the RC and the final product. The RC is supposed to be “feature complete,” however. In other words, the services are supposed to be the same, but by the final build they’re supposed to be more streamlined and with the bugs worked out.

    Many programs won’t release their final versions of things that are compatible with RTM until Windows 7 goes on sale to the public in October.

    In some cases you might also need to be sure you’re installing as an administrator. And in others you could indeed be having issues with things like the recovery partition that Windows 7 can install with the higher end versions.

    You may need to reinstall Windows using one of the “tricks” that makes the recovery/Bitlocker files put on the main partition along with the OS. There will assumably be greater support / info for things like TrueCrypt as Windows 7 get formally released, too.
