While installing LP360 for ArcGIS receive the error, “Module C:\Program Files (x86)\Common Files\QCoherent\LASExt.dll failed to register. HRESULT -1073741819”. Multiple errors of a similar nature for other DLLs also occur if one continues with the installation.
If on a Windows 7 or Server 2008 R2 operating system with Windows Update KB4041686 or similar installed:
- Continue through the errors to complete the installation.
- Open an elevated command prompt by right-clicking on Command Prompt and selecting “Run as Administrator”
- Change directory using “cd “c:\Program Files (x86)\Common Files\QCoherent” “
- Execute regall.bat to register the DLLs that erred when using the MSI by typing “regall” at the command prompt.
Probable Resolution #2:
Roll back the Windows updates. Install LP360. Then install the Windows updates.
Probable Resolution #3:
There may be something else going on with your machine configuration that is interfering with the proper installation of LP360. From an elevated Command Prompt (right-click on Command Prompt and select “Run as Administrator”), please run the following command using the full path to where you have the 32-bit MSI and writing the log file to a directory that you can access.
msiexec /i “LP360forArcGIS_v2017.1.54.7.msi” /L*v “log32.txt”
