Having trouble with the Building Life Cycle Cost (BLCC) Programs software? See the problems and solutions below to troubleshoot BLCC software issues.
Problem: Receiving "Error loading the jvm.dll" error message when attempting to install the BLCC software.
Solution: The BLCC installer looks for a valid jvm.dll file in the jre path under bin/server or bin/client. So check what path is set for java in System Properties, Environment Variables, System Variables, Path and modify the path if necessary to point to the correct path where jvm.dll can be found. Or reinstall Java and ensure it is installed for "all users" in a folder for which "all users" have access, then try to install BLCC again. Make sure to uninstall both Java and BLCC because if you install either in multiple locations, there could be issues.
Problem: Unable to run the installer.
Solution: Make sure that java 1.8 or greater is installed. The installer will not run with older versions of java.
Problem: Receiving "Download.app is damaged and can’t be opened" error message when attempting to install the BLCC software on a Macintosh operating system.
Solution: Visit the Tech Recipes website for instruction on how to change your security settings to allow your system to load the software.
Problem: Project files are not saving.
Solution: On newer versions of Windows, files can't be saved in the projects folder when it is located in program files. The easiest fix is to right click on the BLCC icon and select "Run as administrator." Running the program in this mode will allow you to save to the projects folder.
You can also save the file outside of the BLCC directory (and outside of program files). The Documents folder will work.
If you have additional problems with BLCC or questions about these solutions, contact the FEMP website contact.
Problem: A non-domestic user can install BLCC but cannot open any existing or new files.
Solution: If you are a non-domestic user, it's possible that your date format in your location is different than that in the US. BLCC expects the long date to be in Month Day, Year format but these users have it set for Day Month Year. There are a couple potential solutions:
(1) We have provided example files that have the right date format for the UK, which might match your date format (day/month/year). Please open BLCC, click on File -> Open -> FilesForEnglish(United Kingdom). Then open any of the files available (they have the same names as the US versions). If it opens successfully, then the date format is the same as your computer and you can used these example files as the basis for your analysis.
(2) If option #1 does not work, then you can try changing your home region on your computer to the US and then try to run BLCC as you did initially. Before running the software, change the regional format to English (United States). To do this, go to Regional and Language Options under the Control Panel. Then select Regional Options. You can do a quick web search and find more detailed instructions on how to do this at Winaero's website.
Problem: Issues installing BLCC or opening BLCC after installation.
Solution: If you are having issues installing BLCC, it could be an issue related to Java. NIST provides two versions of BLCC, one with a virtual machine that runs its own version of Java when you open BLCC (this is the version you download from the direct link on the BLCC main page), and a second that uses the version of Java on your local machine. Uninstall any versions of BLCC that you have on your machine before you try to reinstall it.
Problem: Issues downloading or installing BLCC.
Solution: If you are having issues downloading or installing BLCC on your machine, it could be network-related security restrictions. If you can download BLCC but cannot install it, you may not have the software installation rights. If you cannot download BLCC, it could be because executable files by be blocked by your network security from downloading. In either case, you could try to download the ZIP file of the BLCC folder that we provide on the NIST BLCC webpage. Once downloaded, extract the folder and you will be able to access BLCC directly from that folder (note a shortcut will not be created for you). This approach allows a user to avoid the installation process, although you do have to download a ZIP file, which can also be blocked by network security. If you are unable to download any of the files at the link below, please contact Joshua Kneifel to determine the most appropriate secure file share option (e.g., Google Drive, Box).
