Wonderware Intouch Compatibility Matrix -

“The one where engineers annotate their own findings. Look at the entry for InTouch 10.1 SP3 with Historian 9.0 on NTFS volumes larger than 2TB. There’s a handwritten note—I swear it’s handwritten in the PDF—that says: ‘SQLite timestamp mismatch. Set registry key: HLM\Software\Wonderware\Historian\UseSystemTime=1.’ ”

She clicked “Go.”

Three: The new edge servers she’d just unboxed ran Windows 11 IoT Enterprise.

She pulled up the PDF on her tablet. Wonderware InTouch 10.1 , it read. Supported OS: Windows 7 SP1, Windows Server 2008 R2. Unsupported: Windows 10 21H2, Windows 11 (all builds). wonderware intouch compatibility matrix

“The Matrix says it’s impossible,” Marta said, closing her laptop. “But the Matrix doesn’t have a footnote for stubborn engineers.”

She scrolled the Matrix. No mention of historian issues. That meant it was either a new problem or an undocumented one. She called an old colleague—Dominic, who now worked at a Wonderware (no, AVEVA, she corrected herself) integrator in Baton Rouge.

She smiled, knowing she’d just added her own entry to the ghost in the machine. “The one where engineers annotate their own findings

Then, at 3:22 PM, the historian stopped logging.

Two: The legacy SCADA system—Wonderware InTouch 10.1—was older than some of her interns.

She applied the fix. Then she exported the InTouch application from the Windows 7 machine—a sprawling, 8,000-tag monstrosity controlling fermenters, cookers, and the new CIP system. She imported it into a virtual machine container she’d spun up on the Windows 11 edge server. The container ran a simulated Windows 7 environment. It was ugly. It was unsupported. But the Compatibility Matrix had a second footnote: “Legacy applications may function within Type 1 hypervisors if network stack isolation is enabled.” Supported OS: Windows 7 SP1, Windows Server 2008 R2

The InTouch startup screen appeared. Alarms initialized. Tags went live. The bourbon aging line’s simulated temperature curve rose smoothly on the trend chart.

No one had ever told her that. The official manual was silent.
