Previous versions of BridgeComposer are available for use in case you have difficulties with the current release.
For easy download and install, we recommend BCInstaller. Simply run BCInstaller, go to the "BC Website" tab, select the desired version, and click the "Download & Install" button.
Alternatively, you may download the following:
|Archived Version||Release Date||Notes|
|BridgeComposer 5.44||2013-07-08||Last version that runs on XP without SP31|
|BridgeComposer 5.42.2||2013-04-08||Last version that runs on very old systems2|
If you don't use BCInstaller, and you are moving from one version of BridgeComposer to an older version, you will need to uninstall your current version before you install the older version. One way to do this is by starting your current BridgeComposer, using the Help→License menu command, and clicking the Uninstall button. You may also uninstall using the Windows "Programs and Features" control panel. Either way, choose the option to "KEEP all user settings and KEEP license key".
Windows XP systems that have not been updated to "Service Pack 3" (SP3) or later may experience a "blue screen" system crash when starting certain versions of BridgeComposer. If you experience this problem, update your Windows XP system using Windows Update, or try BridgeComposer version 5.44 or older.
We believe that this problem has been circumvented in BridgeComposer version 5.59 and later. If you are affected, please report your experience to firstname.lastname@example.org.
All versions of BridgeComposer run fine on Windows XP with "Windows Update" patches up-to-date.
If the file C:\Windows\System32\Sxs.dll has a version less than 5.1.2600.5512, your OS is not up-to-date.
Very old systems may experience an "illegal instruction" fault (0xC000001D exception). This is due to the more recent versions of the Microsoft library software using CPU instructions from an enhanced instruction set.
If you experience this problem on an aged system, try BridgeComposer version 5.42.2 or older.
My HP 7285 desktop, purchased in November, 1996, has an "original" Pentium CPU (P5 microarchitecture, 200 MHz). It runs BridgeComposer 5.42.2, but it does indeed get an illegal instruction fault when attempting to run newer versions.
The fault typically occurs on a CMOV (conditional move) instruction, which was not added to the x86 instruction set until the Pentium Pro (1995), Pentium II (1997), and Pentium M (2003).
