Known bugs
The bugs published on this page are mainly computational bugs that affect the calculation results. For each bug there is a plan for when the bug will be fixed.
As a service to our customers we sometimes make a patch for a bug. We do not publish these patches on this page. To get access to a patch, please contact our support. The patches might not always be well tested and should only be installed by customers experiencing the specific problem that the patch fixes.
Bug fix version
With certain intervals we collect fixed bugs into a Bug fix version that is installed in the same way as a new version. A Bug fix version has a four digit version number, e.g. 2.0.0.1, and includes fixes for both computational bugs and other bugs.
Windows File Explorer: A recent update to Windows is causing IDA Tunnel to crash when File Explorer is opened, for example when using “Save As…”, “Open…”, or “Import CAD”.
Workaround:
- Delete DLL files "msvcp140.dll" and "vcruntime140.dll" from the folder "bin" in the IDA Tunnel installation folder. For example "C:\Program Files (x86)\Tunnel\bin"
- Test if IDA Tunnel is functioning as intended.
- If IDA Tunnel continues to crash:
Go to Latest supported Visual C++ Redistributable downloads | Microsoft Learn and install the X64 Redistributable package.
Introduced in IDA Tunnel 2.0
Will be fixed in the next version of IDA Tunnel
Sending Project Files to Support: In Outlook 2024, issues have occurred when sending project files to EQUA support - emails are not always delivered successfully.
Workaround: Instead of using the built-in email function, users should follow these instructions.
All versions of IDA Tunnel are affected
Long-term simulation: The seasonal step of Long-term simulation crashes when tunnel section consists of a transversal duct, jet fan, filter or a profile point.
Introduced in IDA Tunnel 2
Fixed in IDA Tunnel 2.0.0.1
IDA Tunnel startup crash with SentinelOne on Windows 11: There is a known issue where Sentinel Agent, part of the SentinelOne anti-virus software, may cause ida-tunnel.exe to crash during the startup of IDA Tunnel. This occurs because Sentinel Agent injects itself as a DLL, which then attempts to access a null pointer. So far, this issue appears to be limited to Windows 11 (specific versions affected are currently unknown).
Workaround: Add an exclusion for ida-tunnel.exe in SentinelOne to prevent the crash.
Note: This does not appear to be Sentinel Agent flagging IDA Tunnel as malicious. Instead, it is caused by a problem in Sentinel Agent’s DLL injection behavior, which is outside of our control.
All versions of IDA Tunnel are probably affected
