Trying to start / run a DLL that is not there: logiLDA.dll in Other Software Programs Posted August 10, 2019 1st. There was a problem starting C:\Windows\System32\LogiLDA.dll. This error occurs due to the incompatible version Logitech software, more specifically Logitech Download Assistant. This belongs to the Logitech mouse, one of the most commonly used mouse among the PC users. I have the latest for my MX Master mouse, but the error never goes away or get fixed, manually or with IOBit. The mouse automatic used windows10 drivers and then Logitech asked to install their lastest...and it all started the error. 2nd. issue is IOBit not see this error either. OneDrive is not being use(I hate this product) so I turned it off. I can't find or do a fix for this pop-up error, every startup the sound 'honks' to remind me as with the LogiLDA.dll error.
